How can I uncorrupt a file

Hello Charlotte,

I'm sorry to hear about your file issue. Please try the following solutions:

Automatic Repair (File Recovery Mode):
When you open a corrupted workbook in Microsoft Excel, it automatically starts File Recovery mode and attempts to repair the workbook.

If File Recovery mode doesn’t start automatically, follow these steps:
Open Excel (Just the app, not the corrupt file) > Click File > Open.
Navigate to the location and folder containing the corrupted workbook.
Select the corrupted workbook.
Click the arrow next to the Open button, and then choose Open and Repair.
If successful, this method will recover as much of the workbook data as possible.

Manual Repair:
If automatic repair doesn’t work, you can try these manual methods:

Revert to the Last Saved Version:
If the workbook became corrupted before you saved your changes, you can revert it to the last saved version:
Click File > Open.
Double-click the name of the workbook you have open in Excel.
Click Yes to reopen the workbook. It will open without any changes you made that might have caused corruption.

I hope this helps.

Kind regards
Marius Barnard
